PC bootlooping after installing new GPU

[Thuglyfia]

I7 6700k

Asus Z170-A

Gtx 1070/Gtx 470

Gskill ripjaws V 16gb 2x8 3200mhz

Evga 750BQ bronze

2x Samsung 850 Evo 500Gb

2xWD blue 1Tb

My 1070 developed a nasty coil whine so I've rma'd it. 

 

My system was running fine when I decided to play some Apex legends with friends thinking that the integrated graphics would be enough as it was able to handle overwatch at minimum settings 1080p. I was able to get about 40fps at 720p but there was some artifacting which was just black squares that appeared and dissapered.

 

I then remembered that I had an old Gtx 470 that my friend had given me awhile ago after I built my PC but before I had purchased my current GPU; when I put the 470 in my system it caused it to boot loop. After removing the 470 I could get to the bios but upon exiting the bios I'd just be sent back.

 

I don't know what to do, I've googled my problem and nothing I've found has been of any help. I tried pulling the cmos battery but that didn't do anything either.

use on the board graphics and try and boot into windows and use DDU to remove the nvidia drivers.

I've tried that, it no longer bootloops after removing the GPU, but I can't get past the bios. I have now narrowed the issue to either my boot drive or the m.2 bus. Somehow it seems I've fryed one or the other, possibly both while replacing the gpu
